To aZZ whom it may concern.-

Be it known that we, DENNIS L. MoKIN- NEY and GEORGE W. HENDERSON, citizens of the United States, residing at Fairmont, in the county of Marion and State of West Virginia, haveinvented a new and useful Window-Sash Fastener, of which the following is a specification. T This invention relates to window-sash fasteners.

a The Object of the invention is to provide a novel,- cheap, and efficient form of windowsash fastener which will operate positively to lock the two sashes together against movement relatively to each other or both sashes to the j amb, whereby when a predetermined adjustment of either or both of the windowsashes has been secured it cannot be changed from the outside of the window.

- vertical transverse section through one of the meeting-rails of the sash and through the attachment.

Referring to the drawings, A designates the meeting-rail of the lower-sash; B, one of its stiles; O, the meeting-rail of the upper sash; D, one of its stiles, and E one of the j ambs of the frame. the usual or any preferred construction, and therefore need no further description.

Secured to the right-hand portion of the 1 upper side of the meeting-rail A and to the face of the stile B is the window-fastener constituting the subject-matter of the present invention.

This fastener embodies a plate 1, which is secured to the meeting-rail and is provided with a tongue or extension 2, disposed at right angles thereto and secured to the stile B. The plate is provided with four upstanding mar inal ears 3, 4, 5, and 6, which are orificed for ti 7 and 8, which, as shown in Fig. 1, are dis- These parts may be of I e reception of a pair of bolts posed at right angles to each other, the bolts 7 being designed to engage seats or sockets 9 in the j amb E and the bolt 8 to enga e seats or sockets 10 in the stile D. Pivota ly connected with a lug 1 1 on the ear 3 is a lever 12, with the shorter end of which is connected, by a screw or rivet 13, the bolt 7, the longer end of the lever being curved downward over the edge of the meeting-rail, thus to be within convenient reaching distance of the operator. In order to cause the bolt 7 normally to engage the seats 9, there is a coiled spring 14 provided, which is held in position byteats 15 and 16, carried, respectively, by, the ear 3 and the lever 4. I 1

'Pivotally connected with a lug 17, project'- ing from the extension 2, is a lever 18, the upper end of which is connected, by a pin or rivet 19, with the bolt 8,a coiled spring 20, engaging the inner side of the lever, operating to cause the bolt 8 always to enga e with'the seats 10, the said spring being he d in place by engaging a teat 21 on the extension and a like teat.22 on the lever.

When the lower sash is to be raised or lowered, the two leversare actuated to move the bolts 7 and S out of engagement with the seats 9 and 10 whereupon the said sash may be moved to the desired position, and upon the levers being released the bolts will again engage with the seats and the j amb and the stile D. Should it be desired to raise or sary to move the bolt 8 out of engagement with the seat 10, whereupon the sash may be adjusted as desired and locked in such adjustment by releasing the lever 18-and permitting, the bolt 8 again to engage with one ofthe seats 10.

It will be seen from the foregoing descrip- A window-sash fastener comprising a onelower the upper sash, it will only be neces- I Too piece supporting-plate embodying two pairs f of oppositely-alined upstanding orificed ears 7 with the bolts and projecting downward,

when the fastener is positioned upon a Window, thereby to be within convenient reach of the operator, and springs engaging the pintles on the ear and tongue and similar pintles on the levers to cause the bolts automatally to assume locking position.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
